File naming convention
File names for ORRI tiles are keyed to the USGS 15-minute topographic maps. For example, "bara2nwqs.tif" is the tile for the northwest portion of the Barrow A2 quadrangle. For more information, see "ifsar_filenames.txt" on DVD 4.

File names for GIS layers of the Barrow Peninsula begin with "bp." File names for GIS layers for the smaller area of the Barrow Triangle begin with "bt." Names for most of the raster layers also include a number indicating horizontal resolution. For example, "bp05_dsm" is the full-resolution version of the DSM with 5 m grid-cell spacing.
